Answer:

Step-by-step explanation:

Subtract  

6 u  from  2 u .

− 4 u + 9 = 19

Move all terms not containing  u  to the right side of the equation.

− 4 u = 10

Divide each term by  − 4  and simplify.

u = −  [tex]\frac{5}{2}[/tex]

The result can be shown in multiple forms.

Exact Form:

u = −  [tex]\frac{5}{2}[/tex]

Decimal Form:

u =− 2.5

Mixed Number Form:

u = −  2 [tex]\frac{1}{2}[/tex]
